A person who knows the difference between right and wrong, but doesn't give a damn. Shows no morality and no emotions towards others, including love, guilt or hatred. Would happily destroy anything or anyone merely for personal pleasure.

Samuel B Slater from fresh unit is a total psychopath, but is also very intelligent.

In short, a wolf in sheep's clothing, a predator in disguise. Psychopaths are generally thought of as serial killers, but most are not even criminals; necktie psychopaths wreak havoc in the office, ruthlessly manipulating and charming their way to the top.
Psychopaths are obsessively meticulous, are calm and fearless, and are able to lead a double life in which family and friends see one person... and other people see a very different side. Immoral, perverse, and criminal, they know right from wrong but they get a thrill out of defying the law and moral codes.

Similar to a sociopath, except that psychopaths are born while sociopaths are generally made and they seem to be two sides of the same coin; psychopaths are temperamentally devil may care, are cool and self-controlled, and cannot internalize social norms; sociopaths have relatively normal temperaments, are more easily agitated, and their problems are generally the result of environmental and social factors (unstable childhoods, the wrong crowd, extreme high or low intellect, etc); psychopaths are obsessively meticulous while sociopaths are more sloppy and erratic; psychopaths feel nothing for others while sociopaths can feel empathy in particular contexts; psychopaths are able to fool people for years while sociopaths are more easily exposed. Both will get what they want, regardless of who stands in their way.

Psychopath is a person that is mentally unbalanced and poor human control as they have a deranged and disturbed mind; their personalities are crazy demented, perverted, criminal, amoral and unpredictable. They exhibit antisocial behavior, inability to love or establish meaningful personal relationships, they're often prone to committing violent acts, have extreme egocentricity and show no remorse and empathy for anything that they have done, that is either embarrassing or crazy and don't care about anyone who they hurt as they care about nobody else, except for themselves. They fail to learn from the consequences of bad experiences whenever something has gone wrong as they're impossible to be disciplined and they don't learn from their past mistakes and take it out on others.

A psychopath can also be a sadist as well, which can make them even more dangerous and more violent. As there is a difference a sadist on its own can feel a small bit of remorse of that a psychopath cannot.

And most psychopaths are killers and dangerous, not all psychopaths are serial killers and homicidal maniacs.

A psychopath is on the same level and has similar traits to a sociopath such as being manipulative and inability to feel remorse and shame, but psychopaths are worse and most of them are murderous (but not always) while sociopaths are against society.

You're a psychopath! What you did was wrong!! You don't care what you did.. YOU'RE MAD!!!

Psychopathy is in many cases also linked being a Sociopath, having Antisocial Personality Disorder, and Pseudopsychopathic Personality Disorder (also known as Frontal Lobe Disorder). The last of which is caused by lesions of the frontal lobe

Being a psychopath doesn't mean you're going to be in prison for mass-murder or that you only resort to violence.

Generally an intelligent, heterosexual, socially concerned male with adequate amounts of male hormone but who's sadly been hit with the ugly stick at birth. They go through most of their adolescents and young adulthood severley tormented, discriminated and rejected by both sexes because of personal appearance flaws, but its the female rejection which would later demonize them forever. Then from about ages 25+ these somewhat psychologically damaged and bitter individuals begin to despise all human rights and wrongs especially the 'asthetic law' which places the ugly away from the goodlooking. The end result being a sexually frustrated, deprived lonely individual whos only en-route to eden and out of depression is to go on a ballistic rampage for nothing more than self gratifcation, revenge and power.

Cop; Man there's something about that psycopaths case that all us males can relate and on a higher note which also explains the rife media interest. I conclude the guy had no self control!.. Thats all. In fact I'm glad I met my Betty Davis way back on prom night.
